My naim audio cd3.5 player has developed a fault, whereby when you load a cd in, it dosent always start spinning and dosent always play - you have to keep opening and shutting the cd tray until it starts! It also then makes a periodic noise whilst playing.

There are bad solder connections inside the receiver that are causing the protection circuit to kick in. This is a simple resoldering job and should only cost the labor rate at a local service shop.

SOURCE: CD player fails to read

This is a typical problem when the laser " eye" gets dust on it, unplug the unit and you can try to remove cover and spray the optical pickup "eye' with canned compressed air or other type of optical cleaner found at say like radio shacks, I have solved many disc reading errors with this method

SOURCE: I load the cd's and

Hello,

Obviously, the problem is from the laser (lens) of your player. The lens is weak such that it cannot load data on discs. Its spinning, trying to load, but can't because of the weak laser.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all CD's again.

Good luck.

Hello,
The tray drawer is opperated via a "Belt" off a drive motor. The hum is good as it would appear the drive moyor is working, but it would appear the drive belt as come off or snapped.
Your nearest audio repair shop could repair this for minimal cost.

Philips mcm9 system won't read any cds. It says "reading" but nothing else happens and even says that when there is no cd in slot, radio & tape are both working and cd player was working...


In most cases when the CD does not play it is possible that the optical head is a suspect. Sometimes it might pick up ordinary audio CD but will not play other formats. This indicates that the optical head is weak and so there is no detection or scanning of the CD . If the optical is working the tracks will be read immediately but with no scanning the laser head can be defective.

If the no disc comes even without a disc in the player you must check and see if there is a mechanical fault specially in the loading section that seems to trigger the CD mode to work.

Also check to see the main motor as it will not work in some cases as unless the tracks are read the drive motor will not work with signal from the processor. Also in some cases the central motor base can shift and so the distance to the disc can be more resulting in low detection. You can pull up the spindle to come closer.
Sometimes certain cleaner disks will not be tracked to run for cleaning as it will not be read and so will reject. Hence it is ideal to manually clean the laser head eye using a cleaning swap /cotton bud with gentle pressure on the lens eye.
If there is no result then watch if the CD spins or tries to spin. If so the board seems to work unless a test is taken on the main board but the possibility of a defective optical head can be the suspected fault.
If any of the above seems otherwise we must recheck with possibilities of a malfunction of the main processor board

My Cds wont play in it , the screen lights up but all it dosent play discs !


It may only play CD-R fomats. If your CD is an MP3, or data disk with folders it might not work. Try a CD you purchased. If that doesn't work your cd player is probably broken.

Sometimes I get no disc error when insert a cd in my sony cdp-ex100 cd player


Put in an ordinary audio CD and play to notice if the CD is detected. If yes the optical is working, if not there is no laser scanning and the possibility that the laser head can be defective.
Now certain cleaner disks will not be tracked to run for cleaning as it is not read. Hence it will reject. So it is ideal to clean manually the laser head eye using a cotton bud with gentle pressure on the lens eye.
If there is no result then watch if the CD spins or tries to spin. If so the board seems to work unless a test is taken on the main board but the possibility of a defective optical head can be the suspected fault.

I have a marantz cd 67 se cd player.it doesn't always play cd's.it appears that it fails to recognise there is a cd in the cd drawer. also when it does actually play it often stops playing part way through...


Hi dr dray
Your player has a CDM12.1 laser transport fitted to it. They suffer a couple of problems that can be fixed that stop em from working so well. If you are handy with a screwdriver, then I can talk you through it.

Kenwood RXD25 CD player intermitent??


Hi jenoss

Sounds like the unit has either a failing load belt to the cd drawer mechanism,not allowing the transport to fully load the cd. Give the unit a gentle tap just after the drawer closes and see if it resolves the problem.

OR a faulty spindle motor, you will have to take the lid off and after pressing play, give the disc a gentle "kickstart". If it then begins to run, then the motor is the problem.

If you find it is neither of these, get back to me here and I we shall go further

Audio selector does not mute unselected inputs


There is a matrix switching IC on the circuit board that switches and routes the sources. This IC (for the audio) may be damaged, or it is not being properly commanded by the uPC controler. You will have to send the reciever to a qualified service tech to have this verified. Troubleshooting this can get involved if the fault is more than just the matrix IC.
